How long do car air fresheners actually last?

Real-world longevity is shorter than packaging claims in most verified-purchase feedback. Hanging cardboard trees are typically strongest for the first few days and noticeably weaker after one to two weeks. Vent clips and gel cans more commonly stretch to several weeks, and 'extra strength' or larger gel formats last longest. Products advertising 200-plus days should be read skeptically against actual reviewer reports.
